Miller Adds New Blue Lightning™ Low-end TIG Arc Starting Technology to Dynasty® and Maxstar® TIG Welders

Blue Lightning™ high frequency, non-contact arc starting technology positively and consistently initiates a TIG arc at the machine’s lowest output. It increases weld quality and enables welders in critical applications to eliminate the root cause of many rejected welds.

Highlights/Key Facts

Blue Lightning improves arc starting performance and promotes better weld quality in aerospace welding, tool/die welding and other low amperage TIG applications.

APPLETON, Wis., February 1, 2010—Miller Electric Mfg. Co. announced that it has incorporated Blue Lightning high frequency, non-contact arc starting technology on all of its 200-, 350- and 700-amp Dynasty® AC/DC and Maxstar® DC TIG welders. It was previously available only on 200-amp models.

Blue Lightning provides consistent, reliable high-frequency arc starting at all amperages, including as low as 1 amp on Maxstar and Dynasty 200 models, 3 amps on Maxstar and Dynasty 350 models and 5 amps on Maxstar and Dynasty 700 models. Blue Lightning sets the optimal starting parameters based on tungsten size (from 0.020- to 0.250-in. diameter), eliminating operator guesswork.

Blue Lightening technology controls four arc starting variables: amperage, time at amperage, slope time and minimum amperage for various tungsten sizes. This increased control ensures the arc start and eliminates the current over-shoots that cause burn-through. Aerospace welding, tool/die welding and other low amperage TIG applications especially benefit.

Additional Information

Sources of Variability Eliminated

Traditional TIG machines feature a set of HF arc starting points that function in a manner similar to a spark plug gap. Any variability (such as grinding dust, dirt or high humidity) changes the amount of resistance required to bridge the gap.

Miller’s Maxstar and Dynasty welders with Blue Lightning technology eliminate this source of variability because they use solid-state circuitry, special hardware and a high-speed power-switching transistor that work together to create the most consistent HF arc starts of any Miller TIG welder.

During the thousands of arc starting tests Miller conducted while developing Blue Lightening technology, its engineers re-affirmed some existing “best practices to promote good arc starts” and also uncovered new information. These best practices have been compiled into a technical story available on MillerWelds.com.
